We're quite content with the Fujijfilm YV3.3 × 15SA-SA2. 15-50mm.
I've tested the Tamron M13VG850IR 8-50mm, Fujinon DV10x8SR4A-SA1L 8-80mm, and the Computar H5Z2518C-MP 25-135mm. I believe out of those three, I preferred the Fuji in terms of mechanical setup. It just seemed slightly easier to focus. I don't think one really had an image quality advantage over the others.
I will also repeat John's point about the effective PPF in these lenses. It's not the same as a 3-8mm lens. Expect about half. If you don't need the PPF and you're just looking for an overview of make, model, and color, then you could be fine.
As far as a PTZ goes, the optics won't really be any better. I haven't seen a PTZ lens yet that's really better than a long fixed lens. However, if the long range IR is attractive to you, it might not be a bad plan. In our test we found that the IR range was long, but the the camera didn't handle headlights and taillights well, to the point where you could very well lose make and model due to them flooding out the image.
If the entrance is fairly well lit at night (5-10lx), you may be better off with a WDR box camera/lens combo, and you could likely still pull color information at night without the headlights absolutely killing it. They're still going to have an effect, but it'll be lessened with a WDR camera.
OK, let me take this back to the basics then. Below is an overview (via Google Maps) of the are we are working on. As you can see, the building that I am measuring from to the street is 200ft. That building has a dormer peak at around 20-25ft in height. There is one tree in the direct view from that camera angle that would need removed and that has been accounted for. The width of the street at the 200ft mark is 30ft wide. I have not been on site after dark, but they assure me there is ambient light. Best guess is around 10lux. I will have to measure one night, but it is a figure I am comfortable using for arguements sake.
The customer wants pricing two ways:
a) Color make and model 24/7
b) Option A + an ANPR solution (two cameras)
Would you offer a PTZ or a box/lens/housing combo for option A and why?
Let's open pandora's box and ask for suggestions on option B as well.
Just be make sure the camera has auto stabilization. We had a similar project a year ago. At the time we were using the Acti kcm5211 4mp. With the 40mm lens, you saw the picture move with the slightest bit of wind.
